Final Fantasy

So I have started playing Blue Fields from Final Fantasy with my piano teacher this week, and I while I haven't played the game research suggests that Blue Fields is the overworld theme for FF VIII. With this in mind, I'm very curious if there's any meaning or symbolism behind the name Blue Fields as a track name.

The wiki is not very helpful here, as it just says that BF is considered to be unofficially the main theme of FFVIII, despite Nobuo Umematsu stating this is not the case.

In addition, screenshots seem to show the grass to be green with a notable absence of e.g. blue flowers.

Is anyone aware of any lore behind the name of this track at all?

Specifically, I mean this track: ost, piano collections.

Many thanks :D --An avid Final Fantasy music fan
